Fuse NKS000E1

A
q If fuse is blown, be sure to eliminate cause of malfunction before
installing new fuse.
q Use fuse of specified rating. Never use fuse of more than speci-
fied rating. B
q Do not partially install fuse; always insert it into fuse holder prop-
erly.
C
q Remove fuse for "ELECTRICAL PARTS (BAT)" if vehicle is not
used for a long period of time.

D
CEL083

Fusible Link NKS000E2

E
A melted fusible link can be detected either by visual inspection or by
feeling with finger tip. If its condition is questionable, use circuit
tester or test lamp.
CAUTION: F
q If fusible link should melt, it is possible that critical circuit
(power supply or large current carrying circuit) is shorted.
In such a case, carefully check and eliminate cause of mal- G
function.
q Never wrap outside of fusible link with vinyl tape. Important:
Never let fusible link touch any other wiring harness, vinyl H
or rubber parts. CKIT0163E

Circuit Breaker NKS000E3

The PTC thermistor generates heat in response to current flow. The I
temperature (and resistance) of the thermistor element varies with
current flow. Excessive current flow will cause the element's temper-
ature to rise. When the temperature reaches a specified level, the J
electrical resistance will rise sharply to control the circuit current.
Reduced current flow will cause the element to cool. Resistance falls
accordingly and normal circuit current flow is allowed to resume.

IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)

IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
PFP:284B7

System Description NKS000E4

q IPDM E/R (Intelligent Power Distribution Module Engine Room) integrates relays and fuse blocks which
were originally placed in engine room. It controls integrated relays via IPDM E/R control circuit.
q IPDM E/R integrated control unit performs ON-OFF operation of relay, hood switch signal reception, etc.
q It controls operation of each electrical part via ECM, BCM and CAN communication lines.
CAUTION:
None of the IPDM E/R-integrated relays can be removed.
SYSTEMS CONTROLLED BY IPDM E/R
IPDM E/R receives a request signal from each control unit with CAN communication. It controls each system.
Control system Transmit control unit Control part
q Head lamps (HI, LO)
Lamp control BCM
q Parking lamps, license plate lamps and tail lamps
Wiper control BCM Front wipers
Rear window defogger control BCM Rear window defogger
A/C compressor control ECM A/C compressor (magnet clutch)
Cooling fan control ECM Cooling fan

CAN COMMUNICATION LINE CONTROL
With CAN communication, by connecting each control unit using two communication lines (CAN L line, CAN H
line), it is possible to transmit maximum amount of information with minimum wiring. Each control unit can
transmit and receive data, and reads necessary information only.
1. Fail-safe control
q When CAN communication with other control units is impossible, IPDM E/R performs fail-safe control.
After CAN communication recovers normally, it also returns to normal control.
q Operation of control parts by IPDM E/R during fail-safe mode is as follows:

Controlled system Fail-safe mode
q With the ignition switch ON, the headlamp (low) is ON.
Headlamp
q With the ignition switch OFF, the headlamp (low) is OFF.
q With the ignition switch ON, the tail and parking lamps is ON.
Tail and parking lamps
q With the ignition switch OFF, the tail and parking lamps is OFF.
q With the ignition switch ON, the cooling fan HI operates.
Cooling fan
q With the ignition switch OFF, the cooling fan stops.
Until the ignition switch is turned OFF, the front wiper LO and HI remains in the same status
Front wiper
it was in just before fail-safe control was initiated.
Rear window defogger Rear window defogger relay OFF
A/C compressor A/C compressor OFF

IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)

IPDM E/R STATUS CONTROL
In order to save power, IPDM E/R switches status by itself based on each operating condition. A
1. CAN communication status
q CAN communication is normally performed with other control units.
B
q Individual unit control by IPDM E/R is normally performed.

q When sleep request signal is received from BCM, mode is switched to sleep waiting status.

2. Sleep waiting status C
q Process to stop CAN communication is activated.

q All systems controlled by IPDM E/R are stopped. When 3 seconds have elapsed after CAN communi-
cation with other control units is stopped, mode switches to sleep status. D
3. Sleep status
q IPDM E/R operates in low power mode.

q CAN communication is stopped. E
q When a change in CAN communication line is detected, mode switches to CAN communication status.

q When a change in hood switch or ignition switch signal is detected, mode switches to CAN communica-
tion status. F

CAN Communication System Description NKS000E5

CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul- G
tiplex communication line with high data communication speed and excellent error detection ability. Modern
vehicles are equipped with many electronic control units and each control unit shares information and links
with other control units during operation (not independent). In CAN communication, control units are con-
nected with 2 communication lines (CAN H line, CAN L line) allowing a high rate of information transmission H
with less wiring. Each control unit transmits/receives data but selectively reads required data only.
CAN Communication Unit NKS000E6
I
Refer to LAN-24, "CAN Communication Unit" .
Function of Detecting Ignition Relay Malfunction NKS000E7
J
q When contact point of integrated ignition relay is stuck and cannot be turned OFF, IPDM E/R turns ON
parking lamp, license plate lamp and tail lamp for 10 minutes to indicate ignition relay malfunction.
q When a state of ignition relay having built-in does not agree with a state of Ignition switch signal input by a PG
CAN communication from BCM, IPDM E/R lets tail lamp relay operate.

NOTE:
q When the ignition switch is turned ON, tail lamp relay and daytime light relay are OFF.

CONSULT-II Function (IPDM E/R) NKS000E8

CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.
Inspection Item, Diagnosis Mode Description
SELF-DIAG RESULTS The IPDM E/R performs diagnosis of the CAN communication and self-diagnosis.
DATA MONITOR The input/output data of the IPDM E/R is displayed in real time.
CAN DIAG SUPPORT MNTR The result of transmit/receive diagnosis of CAN communication can be read.
ACTIVE TEST The IPDM E/R sends a drive signal to electronic components to check their operation.

CONSULT-II BASIC OPERATION
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1. With the ignition switch OFF, connect CONSULT-II and CON-
SULT-II CONVERTER to the data link connector, then turn the
ignition switch ON.
